mysqli_fetch_array - mysqli_query php ejemplo

No se puede usar mysqli en php flex env en el motor de la aplicación

Question

Recientemente cambié de un env estándar a un env flexible, para poder usar sockets en mi aplicación php. Sin embargo, ahora mi función mysqli no funciona cuando se implementa ...

Así es como se ve la llamada de función y error ...

    $link = new mysqli(
                    null,                                                   // host
                    ''user'',                                             // username
                    null,                                                       // password
                    ''db'',                                           // database name
                    null,
                    ''/cloudsql/myapp:us-central1:sql-instance''      // instance name
                );

¿Me estoy perdiendo de algo? ¿Puedo usar mysqli en un flex env? Aquí están los registros de errores ...

Answer 1

Agregue un archivo php.ini con lo siguiente:

mysqli.default_socket= ''/cloudsql/CONNECTION_NAME'' 

Asegúrese también de que la API sqladmin esté habilitada: https://console.cloud.google.com/apis/api/sqladmin.googleapis.com/overview
